Is Nikon L20 camera good enough to take some absolutely normal, non-artictic pictures during my trip to London? If not, what’s better with price about £100/$164/€116?

I recently got into the hobby of graffiti. After a few days from practicing I’m starting to picture graffiti everywhere. On the walls, ground, mirrors, etc. this never happened before. Its really weird, is it possibly something mental or what?

I recently bought the Canon Powershot A550 as it was affordable, $165 AUD.
Its good and everything but I was wondering if anyone could give me tips on doing photography with a normal digital camera, not one of those expensive ones.
Like techniques and ideas.

thanks

I have a load of MiniDVDs from my Sony Camcorder and I would like to edit them on the computer somehow. The included CD is rubbish.

I need some good software that will take this format, edit it and burn it onto DVD.

Whatever it is, tell me! I will read all suggestions hopefully.
